2015-06-17 | crypto: poly1305 - Pass key as first two message blocks to each desc_ctx | Martin Willi | |
The Poly1305 authenticator requires a unique key for each generated tag. This implies that we can't set the key per tfm, as multiple users set individual keys. Instead we pass a desc specific key as the first two blocks of the message to authenticate in update().

2015-06-04 | crypto: poly1305 - Add a generic Poly1305 authenticator implementation | Martin Willi | |
Poly1305 is a fast message authenticator designed by Daniel J. Bernstein. It is further defined in RFC7539 as a building block for the ChaCha20-Poly1305 AEAD for use in IETF protocols. This is a portable C implementation of the algorithm without architecture specific optimizations, based on public domain code by Daniel J. Bernstein and Andrew Moon.
